Chart templates and values.yaml in Kubernetes - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to reference a value from values.yaml in a Helm template.

Kubernetes

image: {{ .Values.[1] }}

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using keys that refer to ports or counts instead of the image name.

Forgetting to use .Values before the key.

In Helm templates, you access values from values.yaml using .Values. Here, imageName is the correct key for the image name.

2fill in blank

medium

Complete the code to set the number of replicas from values.yaml in a Deployment template.

Kubernetes

replicas: {{ .Values.[1] }}

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using image-related keys instead of replica count.

Forgetting to use .Values prefix.

The number of replicas is usually set with the key replicaCount in values.yaml, accessed via .Values.replicaCount.

3fill in blank

hard

Fix the error in the template to correctly access the service port from values.yaml.

Kubernetes

port: {{ .Values.[1] }}

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using containerPort instead of servicePort for the service port.

Using keys unrelated to ports.

The service port is usually defined under servicePort in values.yaml. Access it with .Values.servicePort.

4fill in blank

hard

Fill both blanks to create a conditional block that checks if replicaCount is greater than 1.

Kubernetes

{{- if gt .Values.[1] [2] }}
replicas: {{ .Values.replicaCount }}
{{- end }}

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using the wrong key for the first blank.

Using 0 or imageName instead of 1 for the second blank.

The gt function checks if replicaCount is greater than 1. This condition controls scaling behavior.

5fill in blank

hard

Fill all three blanks to define a container port using values from values.yaml.

Kubernetes

- name: app-container
  image: {{ .Values.[1] }}
  ports:
    - containerPort: {{ .Values.[2] }}
      protocol: [3]

Drag options to blanks, or click blank then click option'

CTCP

DUDP

Attempts:

💡 Hint

Common Mistakes

Using servicePort instead of containerPort for the port.

Using UDP instead of TCP for the protocol.

Mixing keys for image and port.

The container image is set with imageName, the port with containerPort, and the protocol is usually TCP by default.
